What is a trick?

A priest decides to pay a visit to a nearby convent. The convent is in a run-down neighborhood, and as the priest walks down the street several prostitutes approach and proposition him.

&quot;Twenty bucks a trick!&quot;

These solicitations embarrass the priest who lowers his head and hurries on until he gets to the convent. Once inside he displays his naivet&eacute; by asking the Mother Superior, &quot;What is a trick?&quot;
